Lens used OLYMPUS M.75-300mm F4.8-6.7 II, very happy with the sharpness of this lens, did have some sharpness issues with this lens at the long end. The problem ended up being the UV filter, always used filters on my lenses for protection. The filter was a Hoya Pro 1D and never had any issues with all my previous lenses using Hoya SHMC & HMC filters. Removed filter and problem was gone, tried a Hoya HMC filter and have no issues.

Looking forward to giving the E-M1 and 75-300 a first try and a similar event when I travel to New Jersey to see my daughter and go to an air show at her base, McGuire AFB, during the second weekend of May.
